Redirect language to dir keeping data

[robbie9]

Hello,

Can somebody help me with the following:
Would like to automaticaly send visitors to directories, based on their language, BUT would like to keep the data behind the index.php.

For example:
index.php?banner=1

Tried something like following, but that didn't work.

<?php
$browser = explode(",", $HTTP_ACCEPT_LANGUAGE);
switch($browser[0])
{
case 'us':
include("us/index.php.php?banner=<?=$banner?>");
break;
?>

Please respond with code example, because knowledge of php is not very high.

Many thanks in advance.

Greetings
Rob

<?
$lang=getenv("http_accept_language");
switch($lang)
{
case "us":$dir="us";
}
header("location:./$dir/index.php?banner=$banner");
?>
I think it will work.

A new problem arrives:

Warning: Cannot add header information - headers already sent by (output started

Is it possible to open a new browser with base top?
